Kan du försöka ännu mer att träffa rätt knappar? : En undersökning av deklarativ och procedurell inlärnings- och minnesförmåga hos barn mellan 10 och 12 år.

Enligt den deklarativa/procedurella modellen av språket (DP-modellen), utvecklad av M. T. Ullman, antas de neurala system som underligger det deklarativa minnet också understödja det mentala lexikonet, medan de neurala system som underligger det procedurella minnet antas understödja den mentala grammatiken. Det huvudsakliga syftet med denna studie var att skapa referensdata för två datorbaserade test som avsåg att pröva icke-språklig deklarativ och procedurell inlärnings- och minnesförmåga. Ytterligare ett syfte var att undersöka huruvida könsskillnader i testresultat kunde påvisas, eftersom tidigare forskning har funnit att kvinnor tenderar att ha en fördel när det gäller deklarativt minne.

Hjärtfrekvens och kortisolkoncentration hos valpar under olika typer av valptest :

The aim of this study was to find possible relations between behaviour and physiology for puppies during different parts of a puppy test. This work deals mainly with the physiological part of the study. Thirtysix puppies, från five litters, were tested in a behaviour test where heart rate was measured and saliva samples were collected before and after each part in the test. Saliva and urine samples were analyzed for corisol concentration as an indicatior of stress. The tests were performed during two consecutive days in the breeders' home when the puppies were seven weeks old. In addition, heart rate and cortisol levels were also measured in the bitch since we were interested in finding out if there were any relations between physiological levels in bitches and puppies.

Verbbenämning hos svenska barn i åldern 3;6 till 5;5 år : En studie av prestation på Action Naming Test

Verbbenämning innebär förmågan att benämna en bild utifrån den aktivitet som bilden illustrerar. I tidigare studier har det visat sig att barn tidigt i språkutvecklingen har svårare för verbbenämning än substantivbenämning (Gentner, 1982; Kauschke, Lee & Pae, 2007). Detta förklaras delvis av att verb är mer lingvistiskt komplexa än vad som är fallet för substantiv (Gentner & Boroditsky, 2001), samt att de är svårare att illustrera (Masterson, Druks & Gallienne, 2008). För att undersöka benämningsförmåga används oftast bildbenämningstest och för verb saknas ett svenskt test för barn. Föreliggande studie syftade till att undersöka verbbenämningsförmågan hos svenska barn samt att utröna om den svenska översättningen av Action Naming Test (ANT) är tillämplig på svenska barn.

?Det var en tyst kamp? : En ekokritisk analys om utvandring och fo?ra?nderliga system i Vilhelm Mobergs Utvandrarna

The purpose of this essay is to do an ecocritical reading of Vilhelm Moberg?s The Emi-grants from 1949. By asking and answering the three following questions; How does a system present itself, What are the different reasons for emigration; Why does differentsystem fit some well and some not.By using two articles from Green Planets - Ecology and Science Fiction to illus-trate two different views; Different parts value in an ekosystem and The Ship as an ecosystem. I have also created, based on the literary text four different terms concern-ing the dynamic system; Stable, Static, Unstable and Collapsing systems. I have found that all system goes through changes, some drastic, that changes the way the parts of the systems fit with in it.

Kappa Control with Online Analyzer Using Samples from the Digester's Mid-phase

In the pulp industry, digesters are used to disolve lignin in wood chips. The concentration of lignin is measured and is called the Kappa number. In this thesis, the question of whether an online Kappa sensor, taking samples from the mid-phase of the digester, is useful or not is analyzed. For the samples to be useful, there has to be a relationship between the measured Kappa at the mid- phase and the measured Kappa in the blowpipe at the bottom of the digester. An ARX model of the lower part of the digester has been estimated.

Uttorkning av Betong

This Thesis aims to explore how to integrate an IT-system for facilitating anorganizations work with Continous Impprovements.This is done here by examining and analyzing the process within a handful ofcompanies who seem to have been successful with their own implementations. Thestudy is focused on the implementation of one particular system, "System C2".Simliarities and differences between the companies, and the established rule of thumbfor these kind of activities are focused upon. This to emphasis how another actormight emulate some of the apparent success.Part of the core question is found in the title, since Continous Improvement is oftenseen as a relativly low-risk activity, is it then also possible to take a low-risk slow pathto the implementation of such a system in the entire organization?.

En undersökning i datasäkerhet för hemanvändare - Är det nödvändigt att använda brandvägg?

The emphasize of this study is to evaluate security issues for home users having a personal computer connected to the Internet. It focus on the usage of advantages and disadvantages when using a firewall while connected to the Internet. The hypothesis is that it gives a better protection to install and use a firewall compared not to do so, due to security flaws in the operating system. The prediction was tested on a home user's personal computer. The testwork was divided into two major tests, each of them performed with, respectively without, a firewall. These major tests were divided into five smaller semi­ tests. The first semi­test without a firewall suffered from a virus or worm attack resulting in loss of data and log files.

Etisk medvetenhet i systemutveckling. En fallstudie av systemutvecklarens ansvar i systemutvecklingsprojekt

Many professions, such as doctors and psychologists, have a long history of work practice which have resulted that these professions have created their own ethical guidelines. The IT profession, which can be viewed as a relative young and somewhat immature profession, have yet to accommodate any clear guidelines regarding ethics. It?s therefore imperative to create discussions regarding ethical actions to raise the ethical awareness and also create ethical guidelines. The development of the IT profession is moving forward at a quick pace and it?s important to understand that this rapid advancement is not only changing the profession but also changing the society and the environment.

Säkerhet och integritet i närfältskommunikation

Context. In today?s society we use smart cards in many areas, NFC is a smart card technology that allows contactless interaction between a reader and the tag, the tag is often in the form of a card. NFC can be used for various payment methods or as access card to a building which makes life easier. In previous studies, the technique has proven to be weak to attacks using an NFC reader connected to a computer.

Aktivitet, läggnings- och resningsbeteenden, tillväxt samt renlighet hos kvigor i liggbås respektive djupströbäddsbox :

The aim of this study was to compare activity, lying down and getting up behaviour, weight gain and cleanliness in heifers in cubicles versus on deep-litter. The study was conducted from autumn of 2005 until autumn of 2006 in a commercial organic dairy herd with 340 cows. In 2005 the farm rebuilt half of the young stock accommodation from deep-litter pens to cubicles. The experiment used 150 heifers of the breeds Swedish Red, Swedish Holstein and crossbreeds between these, all born on the farm. The animals were divided into three blocks based on breed and within each block they were sorted after increasing age. The youngest heifer in each block was randomly allocated to one of two groups, cubicle or deep-litter pen.

Effektutveckling i den koncentriska fasen i bänkpress och knäböj

Aim: The aim of the study was to investigate 1RM and what power could be generated in bench-press and half squat concentric at certain percentages of 1RM. Special interest was put to evaluate men (M) and women (K), strength trained (ST) verses non strength trained (EST) in generating absolute power as well as power relative to 1RM.Method: In total 59 subjects mean (± SD) age 24.9 ± 4.1 years divided into four test groups: 20 male non strength trained GIH-students (EST M), 20 female non strength trained GIH-students (EST K), 10 male strength trained - sprinters on national/regional level (ST M), 10 female strength trained - sprinters (ST K) on national/regional level. They did two tests on 1RM and power in events of concentric bench-press and half squat in a Smith machine. In the first test session 3 ? 5 lifts were made to measure 1RM in each event.

Kontext, utvärdering och användarupplevelse : En studie om kontextens påverkan på användarnas respons vid utvärdering av användarupplevelse

In this paper we explore the relations between context and feedback generated in three user-centered evaluations of a flash-based game. Whether it?s the social context, the physical context or the degree of intrusion from the evaluator, they all contribute to the quality of the feedback received. The selection of test subjects is a narrow process, which gives the above mentioned factors different meaning. Contextual factors have shown to influence the feedback given within both usability and user-experience.

En simuleringsstudie för test baserade på Maximum Likelihood- och Maximum Spacingskattningar

Om vi har ett stickprov med X1, X2, ..., Xn oberoende lika fördelade observationer från en kontinuerlig fördelning med fördelningsfunktion F?, där ? är en okänd parameter, är Likelihoodkvottestet (LT) ofta en bra metod för att testa nollhypotesen H0: ? = ?0 mot HA: ?? ?0. För vissa typer av fördelningar saknar dock Likelihoodfunktionen övre begränsning (Ranneby, 1984) och (Ekström, 2013) vilket innebär att testet inte går att tillämpa då. Detta test jämförs med två nyare test, Ekströmtestet (ET) (Ekström, 2013) och Fidelitytestet (FT) som är ett modierat ET, som vi vet fungerar även i dylika fall. Under vissa generella villkor så vet vi att de tre testen är asymptotiskt ekvivalenta.
